The Dimplex AClass is a highly efficient heating system using an air source heat pump. It uses renewable energy from natural sources to provide heating and hot water to the home. A class heat pumps are located outside the property and replace a conventional oil, lp or gas boiler as the main source of heating. For larger properties, they can be installed an existing system to improve its efficiency. Heat pumps quietly and efficiently extract renewable heat from ambient air, whatever the weather to produce hot water for the home’s heating system. By extracting useful heat from the ambient air, Dimplex air source heat pumps can provide 3 4 units of heat for every unit of electricity used to run the heat pump. This means they can reduce domestic heating running costs by 30% compared to oil and reduce domestic heating running costs by 30% compared to oil and reduce CO2 emissions by up to 40% compared to gas.
